8/10 is my rating. This is a 2021 South Korean Reality Show with 12, 35 Minute Episodes.

Synopsis
Viewers got to know and like so many participants from all seasons of heart signal and this provides an opportunity to get to know them a little more and see what has happened for them after they took part in the show. It also provides an opportunity for the participants to reacquaint with friends they met during the show as well as people from the other season. It follows participants from Heart Signal season 2 and 3 as they live their daily lives and they get to meet a "friend" from the seasons and provides a variable amount of funds to meet up with them in a get to know you "date".

Review

I liked getting to see some of the participants from the seasons in their daily lives beyond the regular show. After viewing them in the show over a months time, I had grown attached to some and wondered how they were doing in their lives after the show. Following them through their morning routine was a bit odd. Not sure that was a necessary element. Having them select a friend and a money for their meeting out of a gum ball type machine was unique and interesting. It was very satisfying for participants from the other season to get to meet participants outside of their season. introducing some new people that hadn't been in the heart signal shows was a unique twist. Having the hosts eat what the friends were eating was unique. I don't think it would ever be enough because we got such a glimpse into these people's lives they sort of feel like friends for all the viewers even though they don't know us at all.

We did get to see a lot of "what ifs" in terms of what if this person from this season met that person from that season - what would they think. And I think it was good for the participants to expand their circle of friends that way.

There was not a lot on what happened with the other half of some of the couples from the seasons that were not on this friends show. So you don't get a lot of resolution there. Like did they date for awhile? Are they friends now? If the person did not appear in this Friends show then you don't get to know any more about them which makes sense as they are real people going on about their actual lives. But, as a viewer it's hard not to be curious and just know that any curiosity you have like that, for participants from Heart Signal that are not on Friends - you are unlikely to get those questions answered.

I found their daily routines a little tiring and wanted to fast forward but was afraid I would miss something. It was like "The Truman Show" or maybe interacting with SIMS not to diminish the fact that these are real people but I am sure watching just about anyone make their breakfast and brush their teeth is not all that interesting.

Spoilers*
I watched "Singles Inferno" before "Heart Signal" so it was weird when Song Jia met with Jae Ho in a blind date situation. I think Jae Ho was very manipulative in Singles Inferno and that she led a lot of the male participants on and liked having the attention all focused on her. It causes others a lot of emotional pain from rejection and it kept them from having interactions with others when she was never fully interested in them. It made me worry about Jae Ho because I think he is very nice and sweet. But knowing that Jae Ho was on Singles Inferno after her appearance on Friends indicated that her and Jae Ho did not have a lasting relationship.

We got to see Young joo and Hyun woo spend some time together and make up. It is unclear if they started dating. But it was nice that they mended that relationship as even if they are just friends they seem to enjoy their time together.
